Best NBA commentator...

Bill Walton

His comments are so outrageous they're hilarious.

Worst NBA commentator...

Steve Kerr

Obvious bias against the other teams in Texas (Houston, Dallas). He will do everything in his power to make San Antonio seem like the top of the league. Sorry, but there are only two teams I don't want to face in the playoffs, Minnesota and Sacramento. Spurs, they got nothing. Big bag o' nothing.
